Topological reconfiguration corresponds to an important tool for planning and operation of electric power distribution systems. Considering the distribution operation planning, how much time one algorithm gets an alternative topological status for the system is not a matter of importance, since the main objective assumed involves: power losses reduction, enhancing the voltage profile and increasing...
This paper presents a novel interconnect technology and packaging solution for silicon power devices, along with the virtual prototyping tool created to develop the concept and optimize it in terms of reliability. The technology is based on the use of bumps (i.e., conductive spheres or cylinders) to connect the surface of vertical power components and is characterized, in comparison with standard...
In operation studies of distribution networks, the restoration problem is solved using optimization techniques. However, in planning studies, such as reliability evaluation, the restoration problem is solved considering engineering judgment. Therefore, there is a mismatch between the restoration modeling used in the operation of the network and in the planning studies. This paper presents a method...
In this paper, we propose a cross-layer optimization approach that exploits retransmission diversity in wireless CDMA communications. Conventionally, data packets that are not correctly detected are usually dropped. These dropped packets can be used to help data packet detection. By exploiting all the retransmitted packets, data packets can be correctly detected with higher probability. The proposed...
This paper explores using modular power electronics building blocks (PEBBs) in building power electronics based controllers for utility systems applications. The analysis of the existing and proposed controller functions identifies three basic PEBB converter functions for power system controllers: bidirectional AC switch, bidirectional AC/DC voltage source converter, and DC/DC converter. A hierarchical...
